Hero GP: 6000 mph
Hero GP is a brand new Game Boy Colo(u)r game, released via itch.io for download to play in any emulators but also able to be used on a GBC itself via a flashcart or on an Analogue Pocket. It is obviously inspired by Hang On, but the constraints of the GBC make the game more streamlined, with more immediate controls and with a simpler game structure.

So, completed the first flight with the new controls. They are _significantly_ different than the setup that I have for _Elite: Dangerous_ which isn't necessarily a bad thing. Once I managed to get used to the control scheme the flight was pretty smooth.
Unfortunately I'm gonna need to practice landing and using the rudder pedals a lot because the landing was one of the absolute worst yet. The passengers were not amused, but since we all lived they should be grateful.

Adaptive quantum dynamics with the time-dependent variational Monte Carlo method
We introduce an extension of the time-dependent variational Monte Carlo (tVMC) method that adaptively controls the expressivity of the variational quantum state during the simulation. This adaptive tVMC approach addresses numerical instabilities that arise when the variational ansatz is overparameterized or contains redundant degrees of freedom. Building on the concept of the local-in-time error (LITE), a measure of the deviation between variational and exact evolution, we introduce a procedure…

Existence of Optimal Stationary Singular Controls and Mean Field Game Equilibria
In this paper, we examine the stationary relaxed singular control problem within a multi-dimensional framework for a single agent, as well as its mean field game equivalent. We demonstrate that optimal relaxed controls exist for two problem classes: one driven by queueing control and the other by harvesting models. These relaxed controls are defined by random measures across the state and control spaces, with the state process described as a solution to the associated martingale problem. By lev…

A Learning-based Quadcopter Controller with Extreme Adaptation
This paper introduces a learning-based low-level controller for quadcopters, which adaptively controls quadcopters with significant variations in mass, size, and actuator capabilities. Our approach leverages a combination of imitation learning and reinforcement learning, creating a fast-adapting and general control framework for quadcopters that eliminates the need for precise model estimation or manual tuning. The controller estimates a latent representation of the vehicle's system parameters …

Anarchism and Linux share key similarities in decentralization. Anarchism puts power back into the hands of the people through democratic, decentralized communities and bottom-up unions that organize collectively without hierarchy. Similarly, Linux operates as a decentralized system where no single entity controls the whole; instead, development and decision-making happen through collaborative, distributed contributions from a global community.
They also align in the principle of mutua…

GARG-AML against Smurfing: A Scalable and Interpretable Graph-Based Framework for Anti-Money Laundering
Money laundering poses a significant challenge as it is estimated to account for 2%-5% of the global GDP. This has compelled regulators to impose stringent controls on financial institutions. One prominent laundering method for evading these controls, called smurfing, involves breaking up large transactions into smaller amounts. Given the complexity of smurfing schemes, which involve multiple transactions distributed among diverse parties, network analytics has become an important anti-money la…

Diffusive noise controls early stages of genetic demixing
Theoretical descriptions of the stepping-stone model, a cornerstone of spatial population genetics, have long overlooked diffusive noise arising from migration dynamics. We derive an exact fluctuating hydrodynamic description of this model from microscopic rules, which we then use to demonstrate that diffusive noise significantly alters early-time genetic demixing, which we characterize through heterozygosity, a key measure of diversity. Combining macroscopic fluctuation theory and microscopic …

CatNet: Controlling the False Discovery Rate in LSTM with SHAP Feature Importance and Gaussian Mirrors
We introduce CatNet, an algorithm that effectively controls False Discovery Rate (FDR) and selects significant features in LSTM. CatNet employs the derivative of SHAP values to quantify the feature importance, and constructs a vector-formed mirror statistic for FDR control with the Gaussian Mirror algorithm. To avoid instability due to nonlinear or temporal correlations among features, we also propose a new kernel-based independence measure. CatNet performs robustly on different model settings …

Polarized 6D Movable Antenna for Wireless Communication: Channel Modeling and Optimization
In this paper, we propose a novel polarized six-dimensional movable antenna (P-6DMA) to enhance the performance of wireless communication cost-effectively. Specifically, the P-6DMA enables polarforming by adaptively tuning the antenna's polarization electrically as well as controls the antenna's rotation mechanically, thereby exploiting both polarization and spatial diversity to reconfigure wireless channels for improving communication performance. First, we model the P-6DMA channel in terms of…

Analyticity of Exponential Dirichlet Series and Applications to the Approximate Controllability of Parabolic Equations
In this paper, we investigate the analyticity of a class of exponential Dirichlet series. We then explicitly determine the coefficients of their power series decomposition and provide an estimate for the remainder. As an application, we study the approximate controllability property of linear parabolic equations with locally distributed or lumped controls by employing the moment method, which relies on the exponential Dirichlet series associated with the spectrum of the system's operator.

Tuning Shear Rheology through Active Dopants
We numerically investigate the shear rheology of mixtures of active and passive Brownian particles, with varying fractions of active components. We find that even a small fraction of active dopants triggers fluidization with comparable efficiency to fully active systems. A combined parameter, active energy, given by dopant fraction multiplied by propulsion speed squared controls the shear rheology and glass transition of the active-passive mixtures. These results together provide a quantitative…

Smoothness Estimation for Whittle-Matérn Processes on Closed Riemannian Manifolds
The family of Matérn kernels are often used in spatial statistics, function approximation and Gaussian process methods in machine learning. One reason for their popularity is the presence of a smoothness parameter that controls, for example, optimal error bounds for kriging and posterior contraction rates in Gaussian process regression. On closed Riemannian manifolds, we show that the smoothness parameter can be consistently estimated from the maximizer(s) of the Gaussian likelihood when the u…

Comparative Evaluation of Acoustic Feature Extraction Tools for Clinical Speech Analysis
This study compares three acoustic feature extraction toolkits (OpenSMILE, Praat, and Librosa) applied to clinical speech data from individuals with schizophrenia spectrum disorders (SSD) and healthy controls (HC). By standardizing extraction parameters across the toolkits, we analyzed speech samples from 77 SSD and 87 HC participants and found significant toolkit-dependent variations. While F0 percentiles showed high cross-toolkit correlation (r=0.962 to 0.999), measures like F0 standard devia…

Family-wise Error Rate Control with E-values
The closure principle is a standard tool for achieving strong family-wise error rate (FWER) control in multiple testing problems. We develop an e-value-based closed testing framework that inherits nice properties of e-values, which are common in settings of sequential hypothesis testing or universal inference for irregular parametric models. We prove that e-value-based closed testing strongly controls the post-hoc FWER in the static setting, and has stronger anytime-valid and always-valid FWER-…

Acceleration-induced transport of quantum vortices in joined atomtronic circuits
Persistent currents--inviscid quantized flow around an atomic circuit--are a crucial building block of atomtronic devices. We investigate how acceleration influences the transfer of persistent currents between two density-connected, ring-shaped atomic Bose-Einstein condensates, joined by a tunable weak link that controls system topology. We find that the acceleration of this system modifies both the density and phase dynamics between the rings, leading to a bias in the periodic vortex oscillati…

Specifically, we derive higher-order stochastic expansions, analyze associated inference procedures, and propose a modified HC3 varian…

Controlling discrete semilinear wave equations toward flocks
In this work, we initiate the research on controlling nonlinear waves propagating on lattices from a completely new perspective. We consider nonlinear waves on a lattice as a system of interacting particles and study their collective flocking behavior. By designing suitable feedback controls, we show that any admissible flock can be reached within a finite amount of time. Finally, we highlight the connection between our flocking problem and a minimal-time problem in the framework of nonlinear H…

Mirror descent is a well established tool for solving convex optimization problems with convex constraints. This article introduces continuous-time mirror descent dynamics for approximating optimal Markov controls for stochastic control problems with the action space being bounded and convex. We show that if the Hamiltonian is uniformly convex in its action variable then mirror descent converges linearly while if it is uniformly strongly convex relative to an appropriate Bregman divergence, the…

Canadians: Replace Ardern with Trudeau and use other Canadian touchstones in place of #nzpol and you have an accurate article for Canada.
Which should speak to what Progressives actually need to do here, and everywhere.
"Ardern’s leadership has often been described as emotionally intelligent, compassionate, and people-centred. But compassion is not liberation. Empathy alone does not redistribute wealth, dismantle police power, or decommodify housing. What Ardern perfected was a mode of governance that couched neoliberalism in progressive language. A style of leadership that appeared anti-fascist, anti-racist, and feminist, while presiding over deepening inequality, mass incarceration of Māori, ongoing colonisation, environmental destruction, and a housing system that serves landlords and property speculators.
Ardern’s “politics of kindness” masked a status quo commitment to capitalism and state power. Her government’s housing policies floundered under the weight of market logic. Despite the crisis of homelessness and unaffordability, the Labour government never seriously considered nationalising housing, implementing rent controls, or seizing vacant properties from land-bankers. Instead, they protected the interests of property investors, many of whom were MPs themselves."
